I have a general idea about their difference that cerebrosides have a single sugar while globosides have more than one sugars.
This is the structure of a ceramide (syphingosine and a fatty acid linked through amide linkage).
It's not clear to me that do cerebrosides have a single monosaccharide on only one -OH group of the syphingosine, two monosaccharides on each of the two -OH groups, or one oligosaccharide on only one -OH group.
Likewise I am not sure if globosides have a single oligosaccharide on only one - OH group of syphingosine, or two monosaccharides on each of the two -OH groups, or two oligosaccharides on each of the two -OH group.
If you have any knowledge about this, please share. Thanks.
